Horizontal injection molding machine duo series

servo-hydraulicelectrictwo-platen

Overview
The duo is a two‑platen (two‑platen) injection molding machine series by ENGEL, designed for the efficient production of large-format plastic parts. The platform combines a compact external footprint with a large mould area provided by exposed tie bars and modular injection units, covering clamping forces from 4,500 to 55,000 kN (higher forces on request).

Applications

• Automotive & mobility components (e.g. tail‑light covers, interior trim, battery covers)
• Packaging and logistics (large-volume containers, transport boxes)
• E‑mobility parts and battery housings
• Electronics and technical housings
• Medical technology components and large technical mouldings

Highlights / Key Components

• Control: integrated CC300 machine control with robot and peripheral integration and configurable automation logic.
• Drive: servo‑hydraulic drive with ENGEL ecodrive option for demand‑based pump output and reduced idle consumption.
• Injection unit: modular plasticizing/injection units with quick barrel change, flexible nozzle concepts and optimized screw geometries for high injection and plasticizing performance.
• Clamping unit: two reinforced movable platens with linear or sliding guides, ensuring excellent platen parallelism and reduced mould wear.
• Mould area: exposed tie bars deliver a clean, flexible working area for very large moulds and complex automation.
• Hydraulics: multi‑circuit hydraulics enable parallel execution of main and secondary movements for short cycle times.
• Digital functions: iQ clamp control and other digital assistants to stabilise process parameters, reduce scrap and support tool protection.
• Variants: duo combi (multi‑component/multi‑colour), duo speed (high‑speed large parts), e‑duo (electric injection unit) and other modular options.

Examples / Use Cases (selected)

• duo 12000 US — giga moulding for very large-format components.
• duo 5500 combi M — production of 1,100 L waste containers (example shot weight ~27,500 g).
• duo 700 — multi‑component applications (e.g. tail‑light covers with IMD/foilmelt and clearmelt PUR layer).
• duo combi / duo speed / e‑duo — configurations for multicolour, high‑speed or electric injection‑unit applications.
